+
+ISPConfig version: 3.1.3
+
+This addon adds dns-slave-zones on additional servers after creating a dns-zone
+If you managed multiple servers with ISPConfig but did not use the mirror-function,
+you can i.e. use server 1 for bind and server 2 as a bind-slave. This plugin
+manages the slave-zones on server 2 when you create / change / delete the
+dns-zone on server 1.
+
+Installation
+--------------------
+
+Download the addon to your server and run the install.sh script to install it.
+
+
+Usage
+--------------------
+
+Adjust the following settings in /usr/local/ispconfig/interface/lib/plugins/dns_dns_slave_auto_plugin.inc.php
+
+1.
+//* define your dns-ip(s) that the slave-server should accept the data from (same as NS (IP-address) in Secondary DNS Zones)
+$this->nameservers[] = '192.168.0.1';
+$this->nameservers[] = 'fe80::2';
+
+If your master-server has only one IP, remove one one the lines.
+
+2.
+//* define the server_ids for slave-server(s) (see server_id in dbispconfig.server on the master)
+$this->dns_slave_server_id[] = 2;
+
+If you want to run bind-slave on several servers, use more settings. I.e.
+$this->dns_slave_server_id[] = 2;
+$this->dns_slave_server_id[] = 12;
+$this->dns_slave_server_id[] = 18;
